摘要: Phenol plant waste water containing small amounts of phenol and sodium sulfate is successfully distilled through the addition of recovered sodium sulfate to enhance the volatility of the phenol relative to water; at least a portion of the sodium sulfate is recycled, while a significant portion of the phenol can be returned to the phenol plant for recovery.

摘要: Vapor mixtures containing ammonia, acid gases and water are contacted with aqueous ammonium phosphate solution to separate the ammonia from the acid gases and to permit recovery of the acid gases. This treatment may be performed on vapor mixtures obtained by steam stripping liquids containing ammonia and acid gases.
